  • FIELD OF THE INVENTION
  • This invention relates to an orthodontic treatment apparatus and in particular, to a self-ligating orthodontic bracket.
  • BACKGROUND OF THE INVENTION
  • The science of orthodontics has been advancing at a rapid pace. Stainless steel wires traditionally used to apply orthodontic forces to teeth have in large part been replaced by high-tech alloy wires. These more flexible “memory” archwires employ the use of titanium, niobium, copper and other more efficient materials. Heat activated, these wires allow for lower, longer acting forces with more allowable deflection of the wire to engage brackets adhered to malpositioned teeth. Once engaged, the archwires are maintained within the brackets using steel ligatures, elastomeric ties, and most recently, self-ligating brackets of various designs.
  • Bracket placement has always been important in orthodontic therapy; the introduction of the self-ligating bracket has increased its importance. Because bracket position directly effects the force application of the archwire on, and ultimately the final position of, the tooth, proper bracket placement during treatment is critical. To aid in the positioning of the bracket at a tooth location which will bring the teeth to a desired physiologic final dental arch form, positioning instruments have been developed, indirect bonding has been used, and most recently, computer aided indirect bonding has been introduced.
  • Even using the newest and most advanced types of orthodontic brackets, a treatment visit is still required at about 6 months after the initial application of the brackets in order to refine bracket position to better achieve desired physiologic parallel root form. Using radiographic images for root repositioning guidance, this treatment visit is scheduled for all patients and often needs to be to be repeated during the treatment course, resulting in multiple time consuming bracket repositioning visits.
  • Sliding, reduced friction mechanics, the basis of modern orthodontic therapy, relies on using high-tech memory wires without bends. Because the metallurgic properties of modern high tech wires do not permit bending of these wires to compensate for less than ideal bracket placement, final tooth position is dependent upon ideal bracket placement. Therefore, during the course of treatment, additional time consuming bracket repositioning visits must be scheduled for those teeth that could not accommodate initial ideal bracket placement, further adding both time and expense to orthodontic treatment.
  • Accordingly, there is still a continuing need for improved orthodontic bracket designs. The present invention fulfills this need and further provides related advantages.
  • BRIEF SUMMARY OF THE INVENTION
  • To overcome these bracket repositioning problems, the present invention provides for a design that allows the bracket to be repositioned on a base without having to remove and re-adhere the base to the tooth. The novel design creates a repositionable interface between a bracket archwire slot and the base and can be used on any bracket design, for example, a standard style design requiring separate wire ligation or a self ligating design.
  • The novel apparatus of the present invention is strong, simple to use and allows for multiple options in bracket positioning, both vertically and horizontally. Application of this novel apparatus will reduce the need to reposition brackets by, for example, recementing or rebonding, and will reduce or eliminate the need to place
  • In a first embodiment, the invention comprises a bracket housing having at least two opposing sides, a rear side which is a tooth engaging side and a front side having a cavity for receiving at least one wire and a locking cover plate pivotally attached to the front side of the bracket housing. The cover plate is designed to be moveable from an open to a locked closed position to secure and hold the wire within the cavity of the front side of the bracket housing.
  • In a second embodiment, the present invention provides for an orthodontic bracket system comprising a base plate having a rear side and a front side, the rear side designed to engage a patient's tooth. The base plate further comprises a channel for receiving an archwire, the channel leading to an opening on the front side of the base plate; a cover plate for closing the opening of the channel and securing the archwire within the channel of the base plate; and an element for locking the cover plate in the closed position.
  • In another embodiment, the present invention provides for an adjustable orthodontic apparatus with a self ligating bracket. The apparatus comprises a base plate comprising opposing sides, a first side being a tooth engaging side and a second side for engaging and adjusting the vertical and horizontal position of a connecting plate. The connecting plate has opposing sides; a first side for engaging the second side of the base plate and allowing for the vertical and horizontal movement of the connecting plate as it relates to the base plate, and a second side having an archwire channel for receiving an archwire. A securing device locks the connecting plate to a desired position onto the base plate and a cover plate closes the opening of the archwire channel to secure the archwire within the channel of the base plate. A locking element locks the cover plate in a closed position.

  • DETAILED DESCRIPTION OF THE INVENTION
  • As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms. The figures are not necessary to scale, and some features may be exaggerated to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention.
  • For purposes of this invention, a bracket is defined as any device which is fixed to the surface of a tooth and designed for attachment of archwires or auxiliaries such as for example, springs or elastics; used to transmit forces from these archwires and/or auxiliaries to the tooth and its supporting structures.
  • In most cases, tooth moving forces are stored in the archwire and/or auxiliaries and delivered through a bracket to the tooth and supporting structures by deflection of the archwire or auxiliary from a passive to an active state.
  • Traditionally, a bracket comprises a base; one or more archwire slots designed for receiving an archwire; and occlusal and gingival flanges or wings designed to receive elastic or metal ligatures used to maintain the archwire within the slot. The bracket is affixed to a tooth by direct bonding through the use of a mesh pad incorporated into the back of the bracket or the bracket is welded or brazed to a band which is cemented around the tooth. Newer, self ligating bracket designs incorporate, for example, a sliding door that closes over the slot, thereby holding the wire in place and obviating the need for separate ligatures.
